It doesn't matter whether you can imagine it or not, the fact is it happens. Some men can take it and some cannot. You don't know until it happens.
Some guys meet WGs, fall in love and they retire. Sometimes it doesn't work out and she returns to escorting. I have seen these scenarios many times during my punting days.
Now to answer the question about myself personally... I know what I'm going in for when I punt, I'm paying for a service and when I leave that service is over. Enter the next punter for the same great sevice. I have no emotional attachment that would cause me EAS and I remain a realist. I certainly have a fondness for regulars, but it stops there.
Hypothetically - I meet a girl (outside punting). Fall in love, then discover, after she told me, what she did. I would like to think, ideally, I could take it as it would make me hypocritical being a punter. Truth is nobody knows until they are in it, it's an unanswerable question. It's like when advising a friend to dump his obsessive girlfriend, you see it from an outsiders view, but being involved is different.
I also agree it's nobody's business other than yours and theirs, nobody needs to know what she did, but then again, my exes friend was known for it and family accepted her. They now have a child. Before you ask, she did not know about my hobby
